TSH Receptor Antibody (TRAb) test measures antibodies that target thyroid-stimulating hormone (TSH) receptors. These antibodies can either stimulate or inhibit the thyroid gland, affecting its function. This test is particularly useful in diagnosing and monitoring autoimmune thyroid disorders like Graves’ disease.
Other Names for the Test:
- Thyroid-Stimulating Hormone Receptor Antibody Test
- TRAb Test
- Thyrotropin Receptor Antibody Test
Purpose
- Diagnose Graves’ Disease: Confirms the presence of stimulating antibodies causing hyperthyroidism.
- Differentiate Thyroid Disorders: Distinguishes between Graves’ disease and other forms of thyroid dysfunction.
- Assess Treatment Response: Monitors the effectiveness of treatments like antithyroid medications or radioactive iodine.
- Predict Remission or Relapse: Helps predict the likelihood of remission or relapse in autoimmune thyroid conditions.
- Prenatal Assessment: Evaluates the risk of neonatal thyrotoxicosis in pregnant women with Graves’ disease.
Preparation
- Fasting: No specific fasting is required unless advised by your doctor.
- Inform Your Doctor: Share details about medications, supplements, or recent thyroid treatments.
- Timing: Ideally performed before starting thyroid treatment for accurate diagnosis.
- Avoid Interfering Factors: Notify your doctor if you’ve recently undergone radioactive iodine therapy or received iodine-based contrast agents.
FAQs
1. What does the TSH Receptor Antibody test detect?
It detects antibodies that stimulate or block the TSH receptor, affecting thyroid function.
2. What conditions can this test diagnose?
Primarily used to diagnose Graves’ disease, it can also help in evaluating other thyroid dysfunctions.
3. What do positive results mean?
Positive results typically indicate Graves’ disease but may also appear in other autoimmune thyroid conditions.

Not always. Some patients with Graves’ disease may have low or undetectable antibody levels.
5. How is the test performed?
A blood sample is drawn from a vein and sent for analysis.
6. Are there any risks?
As with any blood test, risks are minimal and may include slight bruising or discomfort at the needle site.
